Question

Two small metallic spheres, each of mass 0.20 g, are suspended
aspendulums by light strings from a common point as shown in
thefigure below. The spheres are given the same electric charge,
andit is found that they come to equilibrium when each string is at
anangle of 6.0°with the vertical. If each string is 30.0 cm long,
what is themagnitude of the charge on each sphere?
1.0000000119
